如何使用捆绑包中的 parcelable 传递一个 class 对象以在另一个 activity 中接收其所有数据？

 public class BlogDetailVO extends BlogFeedVO implements Parcelable{

   PhotoStoryVO mCoverPic;   
   List<PhotoStoryVO> mPhotoStories;
   LocationVO mLocationVO;

public BlogDetailVO(String mId, String mName, String mDescription) {
    super(mId, mName, mDescription);
}

protected BlogDetailVO(Parcel in) {
    super(in);
    mCoverPic = in.readParcelable(PhotoStoryVO.class.getClassLoader());
    mPhotoStories = in.createTypedArrayList(PhotoStoryVO.CREATOR);
    mLocationVO = in.readParcelable(LocationVO.class.getClassLoader());
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    super.writeToParcel(dest, flags);
    dest.writeParcelable(mCoverPic, flags);
    dest.writeTypedList(mPhotoStories);
    dest.writeParcelable(mLocationVO, flags);
}

@Override
public int describeContents() {
    return 0;
}

public static final Creator<BlogDetailVO> CREATOR = new Creator<BlogDetailVO>() {
    @Override
    public BlogDetailVO createFromParcel(Parcel in) {
        return new BlogDetailVO(in);
    }

    @Override
    public BlogDetailVO[] newArray(int size) {
        return new BlogDetailVO[size];
    }
};

public PhotoStoryVO getmCoverPic() {
    return mCoverPic;
}

public void setmCoverPic(PhotoStoryVO mCoverPic) {
    this.mCoverPic = mCoverPic;
}

public List<PhotoStoryVO> getmPhotoStories() {
    return mPhotoStories;
}

public void setmPhotoStories(List<PhotoStoryVO> mPhotoStories) {
    this.mPhotoStories = mPhotoStories;
}

public LocationVO getmLocationVO() {
    return mLocationVO;
}

 public void setmLocationVO(LocationVO mLocationVO) {
    this.mLocationVO = mLocationVO;
 }
}

以上是我的 class，我想从中访问另一个 activity 中的数据，所以如何将它从这个 activity 打包发送到另一个以及如何接收它在另一个 activity?

Answer 1

正在调用 Activity

Intent intent = new Intent(fromClass.this,toClass.class).putExtra("blogDetailVOObj",blogDetailVOObj);

接收中Activity

BlogDetailVO blogDetailVO = getIntent().getExtras().getParcelable("blogDetailVOObj");

Answer 2

将 parcelableExtra 放入 activity :-

DataObject dataobject = new DataObject("key", "value");

Bundle bundle = new Bundle();
bundle.putParcelable("dataobject", dataobject);
startActivity(new Intent(this, DestinationActivity.class).putExtras(bundle));

在目的地 Activity:-

Bundle bundle = getIntent().getExtras();
if(bundle != null) {
    DataObject dataObj = bundle.getParcelable("key");
 }
